问题描述

我试图将由前同事开发的现有Ruby on Rails应用程序（Ruby 2.3.3p222，Rails 5.0.0.1）迁移到JRuby。使用上述Ruby版本，该应用程序运行无任何问题。您可以在附录中找到作为 Gemfile Ruby 的原始Gemfile。

由于我是Ruby的新手，并且不确定出什么问题，因此我提供了到目前为止所做的所有更改（有关生成的Gemfile，请参阅附录中的 Gemfile JRuby ），以将应用迁移到JRuby。

1。替换gem 'pg'

我用

代替了gem 'pg', '~> 0.21.0' 
gem 'pg', '0.21.0', :platform => :jruby, :git => 'git://github.com/headius/jruby-pg.git', :branch => :master

按照jruby-pg的{​​{3}}的指示进行操作。运行bundle install后，我启动了显示错误的应用程序：

LoadError: no such file to load -- active_record/connection_adapters/jdbcpostgresql_adapter

2。 gem 'activerecord-postgis-adapter'

的改编

要摆脱上一个错误，我在行gem 'activerecord-postgis-adapter'后面附加了以下内容：

gem 'activerecord-jdbcpostgresql-adapter', '~> 1.3.9'
gem 'ffi-geos'
由activerecord-postgis-adapter的{​​{3}}建议的

。同样，在bundler install并运行之后，我得到一个错误：

Bundler::GemRequireError: There was an error while trying to load the gem 'activerecord-postgis-adapter'.
Gem Load Error is: uninitialized constant ActiveRecord::ConnectionAdapters::Column::Format

解决方法

我尝试遵循Github page中给出的提示，并用{p1 

gem 'activerecord-jdbcpostgresql-adapter

由于以下错误，我删除了gem 'activerecord-jdbcpostgresql-adapter', :git => "git://github.com/jruby/activerecord-jdbc-adapter.git", :branch => "50-stable", :platform => :jruby ，错误消失了：

gem ffi-geos

最后我可以运行该应用程序，但是，发送POST请求将返回以下错误

该问题与宝石activerecord-jdbc-adapter有关，可以在issue #891中解决。由于所有更改都是在分支50-stable上进行的，因此无需更改Gemfile。该应用程序现在在JRuby中运行：-）
